MACHINE FOR MAKING BRUSHES.

Specification oftLetters Patent No. 18,528. dated October 27, 1857.

To all whom it may concern:

Be it known that I, LEEMoN A. TRIPP, of the city, county, and State ofNew York, have invented certain new and useful Improvements in Machineryfor Making Brushes; and I do hereby declare the following to be a fulldescription of. the same.

The nature of my invention consists in constructing a machine forwiringand sticking the tufts of hair or bristles 1n clothes, scrubbingand other brushes having wood or metal tuft holder stocks or backs, bymeans of a wire carrying needle operated by a crank, or cam, and havingan intermit of motion at each end of the stroke of the needle forallowing time for inserting the tuft of hair in the loop of the wire,and the feed motion of the brush; second, a wire holder grips orpincers, and gripping bar, having areciprocating motion at right anglesto the vertical motion of the needle for the purpose of carrying thewire to the needle and for taking up the slack of the w1re to draw thetuft of hair in the brush stock; third, a loop former, operated by a camon the needle bar crank shaft for opening the wire at the point of theneedle, to allow the tuft of hair to be inserted therein and lastly bythe combination of a carriage for carrying the brush stock, with theneedle, so that the needle will enter each hole in the stock insuccession at the required time,all the said foregoing parts beingoperated automatically by cranks or cams, and cog wheels driven by amain shaft. But to describe my invention more particularly I will referto the accompanying drawings forming a part of this specification, thesame letters of reference wherever they occur referring to like parts. 7

Figure 1, is an end view of the machine. Fig. 2, is a longitudinal outsection through the line .00, 00 Fig. 4. Fig. 3, is a transverse cutsection through the line 10 m Fig. 4:. Fig. 4, is a plan of the tableboard and feed motion. Fig. 5, is a diagram of the needle and grippers,with connection for operating the same.

Letter A, is the frame of the machine, which may be made of wood ormetal as circumstances may require, and B, is the main driving shaft,secured in suitable bearings across the frame of the machine, and belowor under the table board (1?. On the main shaft is a small cog wheel O,which gears into a second and larger cog wheel D, on a crank shaft E,secured in suitable bearings gether, to give vertical 'motion to theneedle K, attached to the head of the needle bar, by means of adjustingscrews for regulating its length of stroke. This needle bar is securedby suitable guide ways L, attached to the frame of the machine, so as tokeep it steady and in its vertical motion in carrying the wire to andfrom the brush. At each end of the stroke of the needle it is allowed tocome to a stop, or remain stationary long enough to allow the loop ofwire to be formed, and insertion of the tuft or knot of hair, when theneedle is up, and of the feed of the brush stock, when the needle isdown, by means of the slot in the end of the rod G, working loosely onthe pin I, in the needle bar, during a portion of the rotation of thecrank shaft. As this intermit of motion in the needle is of greatimportance in brush making, I esteem it a very essential feature of myinvention, and desire to claim it as necessary to the successful workingof this part of the same.

Letter M, is a miter cog wheel, also on the crank shaft E, which gearsinto a second horizontal miter cog wheel N, onthe lower end of avertical crank shaft P, having a connecting rod Q, attached thereto atone end and the opposite to the end of a horizontal sliding bar R,secured to the under side of the table board of the machine, in suitableguide ways. Secured to the back end of this bar, is a bracket or claspS, into which are inserted, parallel with the bar, the ends of a pair ofpincers or wire grippers T, through the jaws of which the wire passesand is fed up to the needle as required for holding the tufts or knotsof hair. These wire grippers are held loosely in the bracket of thesliding bar, and their operations is thus: When the sliding bar drawsback to the end of the stroke of the crank P, the brackets slip back onthe arms of the grippers, thereby closing its jaws to hold the wire, anddraw the tuft or knot of hair into the hole of the brush stock. On thereturn or forward stroke of the sliding bar, the bracket attachedthereto, slips forward till it comes against the back of the aws of thegrippers, to carry them forward, to slack up the wire as the needleascends; but is held from opening, in consequence of thin arms pressingagainst the lower surface of the table board, and a shoulder on thelower side of the sliding bar, till they are carried past a notch plateU, secured to the under side of the table board, when the upper arm ofthe grippers, opens into a recess and comes to a stop, to allow the jawsto open, and the needle to take up the requisite amount of wire from thespool V. At this point they remain at rest long enough for the loop ofwire to be formed, and the sliding bar to draw back, till the bracket onit closes the arms of the grippers to grip the wire, and take it out ofthe notch V, when it is carried back to the end of the stroke to drawthe tuft or knot of hair into the hole of the stock. Letter W, aloop-former, ar-

' ranged so as to work horizontally in slide ways on the upper side ofthe table board, and operated by a lever X, and cam Y, on the crankshaft E. The object of this loop former is to open the wire from thesides of the needle, and thereby facilitate the insertion of the knot ofhair.

a Letter Z, is a carriage for carrying the brush, arranged to work inguide ways Z on the upper side of the table board and having on its sidea rack into which a pawl 6 is made to operate by means of a lever andcam 61 on the vertical crank shaft P, so that at each time the shaft P,rotates it causes the pawl to move the brush, (secured on the carriageby suitable clamps 6 one hole forward for the passsage of the needle toform a new knot or tuft in the brush.

Having now described my invention and its operations I will proceed tostate what I claim and desire to secure by Letters Patent of the UnitedStates:

1. I claim the use of the slot H, or equivalent therefor, in theconnecting rod G, in combination with the needle, for causing it toremain stationary at each end of the stroke of the crank a definitespace of time for the purposes hereinbefore set forth.

2. I also claim the use of the sliding bar R, having a bracket S,attached thereto, in combination with grippers T, operated by thedevices hereinbefore described, or equivalent therefor, for the purposessubstantially as set forth.

3. I also claim the loop former W, operated by means substantially asdescribed, in combination with the needle for the purposes hereinbeforeset forth.
